Sign in to your Collider account If you've already seen Spider-Man: Brand New Day, and even if you don't, you probably know Sadie Sink is playing Jean Grey in the Marvel Cinematic Universe. The Tony nominee and Stranger Things alum is now the third actress to play the iconic character, following in the footsteps of Famke Janssen and Sophie Turner, and she's set to reprise her role when the MCU's first X-Men movie premieres in 2028. Jean Grey is one of the most enduring characters in Marvel's pantheon, perhaps the most recognizable member of the X-Men, and one of the most powerful beings in the history of comic books—it's this last part that we'll be focusing on today. Everyone might know who Jean Grey is, but how many of you know what she's capable of? Her story in the comics isn't easy, further complicated by a series of retcons, but the fact remains that Jean is one of the most powerful characters, to the point where she probably ranks in the top 5 in the entire Marvel Universe. Who Is Jean Grey? Image via Marvel Comics Jean Grey was born into a loving family, her father a college professor, and her mother a homemaker. She's usually depicted as having at least one sister, Sarah, although future storylines have introduced additional siblings. Jean suffers a traumatic event as a child when her friend, Annie Richardson, is hit by a car and killed. Jean mentally links with Annie at the time of her death, entering into a comatose state. It's usually at this point when Xavier enters the scene, bringing her back but blocking her telepathic abilities. If this last sentence made you ick at the idea of Xavier binding a part of Jean's psyche so freely, then you're not alone; it's one of many icky things Xavier does throughout his long tenure as leader of the X-Men, but that's a story for another day. After Xavier recruits her as a teen, Jean becomes a member of the X-Men under the alias Marvel Girl. She is initially the team's only female figure, and pretty much every male member of the team expresses a romantic interest in her. Her longest and most famous relationship, however, is with Scott Summers, AKA Cyclops, with whom she eventually marries and has a few children, albeit in alternate realities because, well, comics. Traditionally, Jean is depicted as a nurturing figure, the caretaker of the X-Men—you know, when her darker, near-almighty, indestructible alter ego isn't in control. Like most other mutants in the X-Men, Jean lives at Xavier's Institute either as a student or a teacher. She is intelligent, well-meaning, and mature, qualities that usually make her Xavier's golden child, the one he's most proud of, and the epitome of what his students should be. At different points in her history, Jean has been part of other teams, including X-Factor and X-Force. During the Krakoa Era, Jean is part of the Quiet Council as part of the Summer table alongside fellow X-Men Nightcrawler and Storm. Also, Jean dies a lot—a lot, a lot. Comic book characters are no strangers to death and rebirths, but Jean is looking at all those in the rearview mirror. Collider Exclusive · Marvel Personality Quiz Which MCU Hero Are You?

REVEAL MY HERO → Your Hero Has Been Identified Your MCU Hero Is…Based on your answers, the Marvel hero who matches your spirit, values, and instincts has been revealed. 🕷️ Spider-ManYou carry the weight of the world on shoulders that are younger than they should have to be — funny, loyal, and endlessly self-sacrificing. You do the right thing not because it's easy, but because no one else will. You understand that responsibility isn't a burden you choose — it's one that finds you. Whether it's a neighbourhood mugging or a multiverse crisis, you show up. Peter Parker's lesson — that great power demands great responsibility — isn't a slogan to you. It's the code you live by, even when it costs you everything. 😈 DaredevilYou fight in the shadows between law and chaos, guided by a fierce moral compass that refuses to let the guilty walk free. You use every tool available — your mind, your body, your faith — to protect those the system overlooks. You've looked into the darkness and chosen not to become it, though the line has never been easy. Matt Murdock's duality — champion in the courtroom, devil in the alley — mirrors your own. Relentless, conflicted, and unwilling to stop. That is exactly you. 🤖 Iron ManBrilliant, driven, and occasionally insufferable — but always the person who solves the unsolvable problem. You lead with your mind and back it up with resources, innovation, and a stubbornness that borders on heroic. You started out looking out for yourself, but somewhere along the way the world became your responsibility. Tony Stark's arc — from ego to sacrifice — is your arc too. You build, you plan, and when the moment comes, you're willing to give everything. Because in the end, you're Iron Man. 💀 The PunisherYou've been through fire that would break most people — and it did change you, completely. What's left is unyielding, relentless, and operating by a code forged in grief. You don't ask for forgiveness, and you don't expect gratitude. You see a corrupt, broken world and you've decided to do something about it, consequences be damned. Frank Castle's war is born from love twisted by loss — and so is yours. Uncompromising and unflinching — the world may not agree with your methods, but your conviction is absolute. ⚡ ThorPowerful, proud, and on a lifelong journey to become worthy of the legend you carry. You lead with strength but have learned — sometimes painfully — that true greatness comes from humility and growth. You're larger than life, yet more vulnerable than you let on. Thor's story is one of transformation: from arrogant prince to worthy king, from isolated warrior to beloved protector. You bring the storm when it's needed — and the warmth when it matters just as much. 🛡️ Captain AmericaYou believe in something bigger than yourself — and you fight for it even when the world has moved on and nobody else will. You don't bully the small guy, and you never stop when it gets hard. Steve Rogers didn't become a hero when he got the serum — he was always one. So were you. Your strength isn't in your fists; it's in your refusal to compromise what's right, no matter the cost. In a world full of people taking the easy road, you're the one who picks up the shield and stands up — every single time. ↻ RETAKE THE QUIZ What Are Jean Grey's Powers? Image via Marvel Comics Jean Grey is both a telepath and a telekinetic. As the former, she can enter other people's minds, project illusions, manipulate and control, astral project, wipe out memories, and incapacitate multiple individuals at once. As the latter, she can move objects with her mind, lift herself to fly, generate force fields, and produce powerful energy blasts. Jean is an Omega-level mutant, meaning her power reaches "an undefinable upper limit of that power's specific classification." Although she was initially just an Omega-level telepath, she has since become an Omega-level telekinetic, too. Also, fun fact: Jean can communicate with animals telepathically! It's now time to talk about the trickiest part of Jean Grey's story: the Phoenix Force. Best described as a cosmic representation of life and death, creation and resurrection, the Phoenix is one of the primal forces in the universe. It has the power to consume entire planets at once, birth new life, and can even rewrite reality. The Phoenix Force resides outside space and time while simultaneously existing within the main universe; it has been described in the comics as the nexus of the universe's psionic energy, which is honestly a pretty accurate description. The nature of the Phoenix's connection to Jean is... difficult. To simplify it, Jean and the Phoenix are separate entities that are inexorably connected. Powers of X #5 explained it best, comparing them to two planets perpetually orbiting each other: sometimes they're closer, sometimes they're far apart, but they are always connected. Jean is generally agreed to be the Phoenix's ultimate avatar; when they're entirely bonded in full harmony, they become the supreme being known as the White Phoenix of the Crown, who exists in the White Hot Room, outside the confines of time and space. The White Phoenix of the Crime experieces all time simultaneously and has complete control over matter and energy itself across the multiverse. How Powerful Is Jean Grey? Jean Grey is a very powerful mutant, even without the Phoenix Force's enhancements. Famously, and romantically, she can hold back Scott's powerful optic blasts, thus looking into his eyes without fear. She has also bypassed Magneto's iconic helmet and, in an incredible display of both abilities, she simultaneously went into Hank McCoy's mind to secure his medical knowledge while telekinetically reassembling Emma Frost's broken diamond form during the New X-Men run. Talk about multitasking! Jean has also proven her strength by assembling Xavier's broken psyche and tanking attacks from the Celestials themselves. With the Phoenix, Jean has devoured literal stars—seriously, that's a very famous comic book panel that you should probably know. The Phoenix has also defeated Galactus in a one-to-one by absorbing the psychic energy of his herald and even of Galactus himself. During the Dark Phoenix storyline, she also healed the M'Kraan Crystal, the nexus to all realities in the Marvel Universe. Recently, Jean literally created a new universe for Moira MacTaggert to live in peace, free from her reincarnation mutation. As previously mentioned, the Phoenix and Jean are life incarnate, meaning they can create life on a cosmic level. The 2010 Women of Marvel: Celebrating Seven Decades Handbook has detailed Jean's powers at length, noting she is capable of manipulating "atomic structures on a cosmic level." The Phoenix fire can manifest even in the vacuum of space, burn intensely hot, and even resurrect the dead. Famously, the Phoenix Force manifests itself as a flaming bird, fitting, considering its mythological origin. So there you have it: it's safe to say that Jean Grey is really as powerful as you've been led to believe. Very few Marvel characters come even remotely close to her, mutant or otherwise. Indeed, above her are only the supreme cosmic deities of the Marvel Universe, like The One Above All or the Living Tribunal.
